To find out, we divide the voltage in the secondary coil by the voltage in the primary coil.

为了找出答案，我们将次级线圈中的电压 级线圈中的电压。

Now, we want to know how the voltage in the secondary coil compares to the voltage of the primary one.

现在，我们想知次级线圈中的电压与级线圈中的电压相。

The secondary coil is designed so that it shoots out bursts of electricity that look like lightning bolts.

次级线圈的设计使其能够发出看起来像闪电的电流。

So if the secondary coil has twice as many loops as the primary coil, it'll have twice as much voltage.

因此，果次级线圈的回路数是级线圈的两倍，那么它的电压将是级线圈的两倍。

If the secondary coil has more loops than the primary coil, so that it increases the voltage, that's called a step-up transformer.

果次级线圈的回路级线圈多，从而增加电压，则称为升压变压器。

We can write this out as an equation for each coil separately, using a subscript P for the primary coil and a subscript S for the secondary coil.

我们可将其分别写为每个线圈的方程式，使用下标 P 代表级线圈，下标 S 代表次级线圈。

The voltage in the secondary coil divided by the voltage in the primary coil is equal to the number of loops in the secondary coil divided by the number of loops in the primary coil.
